WELT-IBEATING MACHINE.

Application filed December 4, 1913.

To all 1071/0772 it may concern Be it known that we, THOMAS H. SEELY and JOHN B. HADAWAY, citizens of the United States, residing at Dorchester and Swampscott, respectively, in the counties of Suffolk and Essex and State of Massachusetts, have invented certain new and useful Improvements in elt-Beating Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to welt beating machines and more particularly to welt beating machines provided with a slashing knife for cutting slashes in the welt. WVelt beating machines of this type at present in commercial use comprise a vibratory welt beating hammer and a reciprocatory slashing knife which acts to cut transverse slashes in the welt extending partially through the thickness thereof. The slashing knife is under control of the operator, so that it may be thrown into and out of operation during the continued operation of the welt beating hammer, and is actuated to slash the welt while the welt is clamped between the work support and the hammer. T 1e hammer engages the welt in the line of action of the knife and in order to permit access of the knife to the welt the hammer is provided with a recess upon the side thereof from which the knife advances, the knife during its operation advancing into this recess in the hammer. This recess in the hammer greatly reduces the welt beating face of the hammer, and serves no useful purpose except at the time when the knife is in operation. In the operation of beating out the welt of a lasted shoe, ordinarily the operator throws the knife into operation only at one or two points in the marginal portion of the shoe.

The primary object of the present invention is to improve the construction and operation of welt beating machines with a view to rendering such machines more effi cient in beating out the Welt.

With this object in view, a feature of the invention contemplates mounting the beater of a welt beating machine, provided with a welt slashing knife and a heater which normally operates 01 the welt at a point in the Specification of Letters Patent.

path of the knife, so that it may be moved out of the path of the knife as the knife is advanced to slit the welt. The heater may be moved out of the path of the knife in any convenient manner during the operation of the knife. This feature obviates the necessity of recessing or cutting away the welt engaging face of the beater to give access of'the knife to the welt and enables a heater to be employed which will act with much greater efficiency than the heaters with which machines of this type heretofore devised have been provided. In welt beating machines provided with a welt slashing knife, the knife is ordinarily actuated to slash the welt while the welt is clamped between the work support and the beater and in carrying out the present invention the heater is moved out of the path of the knife by moving it over the surface of the welt in rubbing contact therewith so that it smooths or irons out th welt.

Other features of the invention consist of certain improved constructions and combinations, the advantages of which will be obvious to those skilled in the art from the following description.

In the drawings illustrating a welt heating machine embodying the various features of the invention in their preferred forms, Figure 1 is a view in side elevation of the machine; Fig. 2 is a detail view in plan illustrating particularly the welt beating hammer and th welt slashing knife and certain parts associated therewith; Fig. 3 is a detail view partly in side elevation and partly in section, of the mechanism illus trated in Fig. 2; Fig. 4 is a detail under side plan view of the parts illustrated in Fig. 2; and Fig. 5 is a detail view partly in rear elevation and partly in section, illustrating particularly the'construction of the hammer.

The machine illustrated in the drawings is a welt beating and slashing machine of th same general construction and mode of operation as that illustrated in the patent to Hadaway, No. 875,171, December 31, 1907. With the exception of the hammer and a device carried by the slide which supports the knife and cooperating with the hammer, the various parts of the machine illustrated in the drawings have substantially the same construction as the corresponding parts of the machine illustrated and described in the Hadaway patent, and reference may be had to the said machine for a full and complete description of the parts not fully described herein.

In the illustrated embodiment of the invention the machine comprises a work support indicated at 1, the forward end of which is shaped to enter the crease between the upper and welt of a lasted shoe, and to support the welt on its upper surface. The welt heating hammer is indicated at 2, and is secured to the lower end of the hammer rod 4 which is mounted in the forward end or head of the hammer lever. A coiled spring 6 surrounds the hammer rod, and engages at its lower end a collar 8 on the rod, and at its upper end an adjustable sleeve 10 which is threaded into the head of the hammer lever and held in adjusted position by a lock nut 12. The downward movement of the hammer rod in the hammer lever is limited by a stop collar 14 threaded on the upper end of the rod.

The hammer lever indicated at 16 is mounted to oscillate on a shaft 18 journaled in bearings 20 in the machine frame. The rear end of the hammer lever is forked to receive an eccentric block 22 carried by an eccentric on the main shaft 24 of the' machine.

The welt slitting knife 26 is secured to the forward end of the knife slide 28 which is mounted for forward and rearward movement in suitable guides in the frame to advance and retract the knife. At its rear end the knife slide carries a block 30 mounted upon a stud 32, secured in the rear end of the knife slide and the knife slide is advanced and retracted by the movement of an oscillatory lever 34 pivoted on a stud 36, having a groove at its upper end in which said block engages. The lever 34 carries a cam roll 38 which engages a cam groove 40 in a cam disk 42 loosely mounted upon a stud 44, projecting rearwardly from the frame of the machine. The cam disk 42 is rotated to advance and retract the knife by means of a clutch connection with a worm wheel 46 which is driven by a worm 47 mounted upon the main shaft 24. This clutch connection between the cam disk 42 and the worm wheel 46 consists of a clutch pin 50, mounted to slide transversely in the cam disk 42 and arranged to engage a segmental slot in the worm wheel 46, so as to clutch the disk to the worm wheel. The clutch pin 50 is moved in a direction to clutch the disk and worm wheel together by means of a spring 52.

The cam groove 40 in the cam disk 42, as shown in Fig. 1, is formed to actuate the knife slide so as to advance the knife in three steps and to withdraw the knife in one step and to hold it withdrawn during a plu- 1,19e,4se

rality of beats of the welt beating hammer. The rotation of the cam disk is so timed with relation to the movements of the ha1nmer that each of the forward movements of the knife takes place while the hammer is in engagement with the welt and the welt is held clamped between the hammer and the welt support. the knife remaining stationary after each advance movement until the harm mer rises and descends again into epgagement with the welt.

The clutch pin 50 is held out of clutching relation with the worm wheel 46, thereby maintaining the welt slashing knife out of action by a wedge 54 upon the rear end of a lever 56 pivoted on a stud 58. This lever is yieldingly supported so as to maintain the wedge 54 between the head of the clutch pin 50 and the face of the disk 42 by a coiled spring 60. The lever is connected by means of a treadle rod 62 with a treadle (not shown) whereby the operator when he dosires to cut one or more slashes in the welt may depress the lever, thereby withdrawing the wedge 53 from between the head of the clutch pin 50 and the disk 42, allowing the spring 52 to actuate the clutch pin to clutch the cam disk and the worm wheel together.

The welt beating hammer in the machine illustrated in the drawings comprises two parts or boaters 64 and 66. The heater 64 is provided with a sleeved shank 68 which is fixed to the lower end of the hammer rod and the beater 66 is pivoted to the beater 64 so that it can swing laterally with relation thereto. The beater 66 is provided with a pivot stud 70 which engages in a bearing in a forwardly extending plate 72 on the beater 64, said stud having a collar 74 secured to the upper end thereof to hold the beater 66 in place. Figs. 2 and 4 particularly show the relative positions of the beaters 64 and 66 when the knife is inactive. It will be noted from an inspection of these figures that the opposed vertical side faces of the forward portions of the beaters are in engagement, and that the forward parts of the lower faces of the heaters form a substantially unrecessed welt beating face. The beater 66 is held in the position illustrated in Figs. 2 and 4 with relation to the beater 64, by means of a spring 7 6 mounted upon the side of the beater 64 and having a forwardly extending arm 78 which engages with a recess in the collar 74. The beater 66 is cut away, as shown particularly in Fig. 4, so as to provide a recess between the heaters 66 and 64 to receive the forward end of the knife when the beater 66 is in the position illustrated in Figs. 2 and 4 and when the knife is retracted.

The knife during its advancing movements moves substantially in the direction of the arrow (Fig. 4) and it will be seen that the beater 66 lies in the path of the til knife when the welt is engaged by the beater. In order to swing the beater 66 out of the path of the knife as the knife is advanced to slash the welt the knife slide is provided with a forwardly extending arm 80 having a cam face 82 at its extremity, which, as the knife slide advances, engages an inclined face SA on the beater 66, and thereby swings the beater laterally or outwardly out of the way of the knife, so as to allow the knife to advance to its extreme forward position. When the knife retracts the beater is restored to the position illustrated in Figs. 2 and 4 with relation to the beater 64: by the spring 76. To limit the movement of the beater 66 in an outward direction, the pin 86 is mounted in the plate 72 so as to extend upwardly therefrom into position to be engaged by a pin 88 mounted on the collar 74. The beater 66 as it swings laterally over the surface of the welt, the hammer at that time being held against the welt with considerable pressure by the spring 6, has a marked smoothing or ironing action on the welt and this movement of the beater assists materially in the beating operation.

It is to be noted that in the above machine the welt engaging face of the hammer is substantially as great as if no knife were employed so that the beating operation may be performed with much greater facility and efficiency than in machines of this type heretofore used. During the action of the knife the hammer does not interfere in the slightest degree with the action of the knife, and the movement of the beater 66 over the surface of the welt as the knife is advanced smooths and presses out the welt.
